WebOS - Touchscreen support

[lmsilva]

Similarly to what you kindly did for Moonlight on WebOS, I would like to request you add touchscreen support to IHSPlay.

Basically, it is missing the ability to use the touchscreen display on my LG StandByMe 27". The discussion in the Moonlight project (here) managed to add touchscreen support to it but, unfortunately, sunshine doesn't seem to handle streaming / mouse touch events when I launch a 800x600 app in fullscreen on it, so I would like to ask that you kindly add support to IHSPlay too, as I believe it will work correctly for me (at least I don't have that crazy touchscreen issue when streaming with Steam Link into an Android box, using the steam link app on it).

Here's the video I recorded for the Moonlight debugging in case it helps others better understand this request: https://www.youtube.com/watch?v=twIxL9agdXs
